The volume of one box is 240 inches cubed, because 12x8x2.5=240. If we multiply this by 2, then the volume of two boxes of detergent is 480 inches cubed.
a) The linear function that models the amount of water after t minutes is given by:

b) It takes 92 minutes to completely fill the pond.
Item a:
- Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.
- Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.
Then, the function is:

Item b:
It takes t minutes to fill the pond, t is found for which:

Then




It takes 92 minutes to completely fill the pond.
